Title: Optical switch
Inventor: SUZUKI YASUHIRO
IPC: G02B6/12
Filed: 1988-02-29
Abstract: PURPOSE:To efficiently switch optical paths by forming a switching part by using a supergrid formed by laminating different kinds of semiconductors alternately, and forming an optical waveguide part other than the switching part by using a semiconductor formed by making the supergrid into mixed crystal. CONSTITUTION:The switching part 4 of the optical waveguide 5 is formed of the supergrid and the remaining optical waveguide part is formed of the semiconductor obtained by making the supergrid where the switching part 4 is formed into the mixed crystal to manufacture the optical switch without any regrowing process. Further, the supergrid is made into the mixed crystal, and consequently an absorption end lambdag before the supergrid is made into the mixed crystal becomes an absorption end lambdag which is shifted to a short- wavelength side after the complete mixed crystallization and when light with nearby wavelength is incident on the absorption end lambdag, the incident light has wavelength lambdain>>lambdag, so that the absorption loss of the mixed crystal decreases. Therefore, the optical switch is switched in this wavelength range to maximize variation in refractive index at the time of the application of an electric field to the switch part and the absorption loss of the optical waveguide part decreases. Consequently, the optical paths are switched efficiently.

Title: Method for driving liquid crystal element
Inventor: YAZAKI MINORU
IPC: G09G3/36
Filed: 1987-03-02
Abstract: PURPOSE:To prevent decrease of contrast by applying a 1st voltage pulse larger than the saturation value of a liquid crystal and the 2nd voltage pulse of the polarity reverse from the polarity thereof in order to unify the arrangement of the liquid crystal molecules to a liquid crystal element in the selection period of the liquid crystal. CONSTITUTION:The 1st voltage pulse larger than the saturation value on the negative side of the liquid crystal is applied at t13 to a scanning electrode 101 to unity the liquid crystal to the specified arrangement in the selection period t11 of the liquid crystal element which holds the liquid crystal in place between the scanning electrode and signal electrode. The 2nd voltage pulse larger than the saturation value on the positive side of the liquid crystal is then impressed at t14 to the signal electrode 102. Generation of a deviation of an electric field in the liquid crystal element is thereby obviated. High-frequency AC pulses are applied to the scanning electrode 101 and the on or off pulse is applied to the signal electrode 102 in the non-selection period t12 and, therefore, the liquid crystal element which is symmetrical on the positive and negative sides is obtd. Since the deviation in the polarities of the high-frequency AC pulses right after the application of the voltage pulses to determine the content of the liquid crystal element in the selection period is eliminated, the contrast is improved.

Filed: 1980-04-10
Abstract: PURPOSE:To prevent malfunction owing to the reflected waves from objects other than the object to be measured and measure distance accurately by provding a blind anone generating circuit for the purpose of eliminating unnecessary reflected waves. CONSTITUTION:After the reflected waves of the ultrasonic waves from the object to be measured are received in a radio receiver 16b, they are supplied via an amplifier 17 to a measuring circuit 15. This amplifier 17 is controlled by the output of a gate 18. Namely, when the output of the gate 18 is of a low level, the output of the amplifier 17 is interrupted. Thereupon, when there are unnecessary reflected waves by projecting etc., a blind zone generating circuit 14 is provided so that the output of the gate 18 is kept at low level for a prescribed time, whereby the output of the amplifier 17 is interrupted. Hence, there is no input to the measuring circuit 15 during this time and therefore the occurrence of malfunction is obviated. Since the effect of the unnecessary reflected waves is not exerted upon the measuring circuit 15, the accurate distance is measured.
